Abstract
PURPOSE:To convert a signal into an optical level and to transmit it to all other CPUs, by providing a own transmission control function and producing the transmission timing and a control signal regardless of the external signals. CONSTITUTION:When a CPU writes data into a local memory, a coincidence circuit 32 and then signals R/W-1 and DBE-1 plus clock signals E-1 and Q-1 are made active respectively to carry out the rising of a signal A of an address circuit 34 and the presetting of a shift register 31. At the same time, the register 31 is turned active via a D-flip-flop circuit 35 and a timer circuit 39. Thus a transmission oscillating circuit 38 makes a counter 37 advance via a gate 36, and a clock signal B is applied to the register 37. The signal B is then converted into an optical data signal of wavelength lambda1 and an optical clock signal of wavelength lambda2 by light emission driving circuits 41 and 42 plus lambda1 and lambda2 light emitting chips 44 and 45 to be transferred to another CPU via an optical fiber 48.
